If you log in as guest is it OK?

It is OK if I log-in as Admin. On any other account the described problems occur!

If you set a different theme is it the same?

Yes also changing themes does not solve the problem.
The Problem is systemwide and occurs on all existing accounts, except Admin!

Question: If I delete the non-admin Account and create a new non-admin account, would the new account automatically overwrite the space freed up by the deleted account, because I have limited memory space?

If you make a new account and add it to the sudo group you can then log in as that account and then delete the problematic account to resolve the issue. Remember to copy any required data from the user's home folders before deleting the account

Hi Andrew,
I misinterpreted your suggestion in that I thought reference being made to the Theme Addons in Firefox.
As the problem was systemwide, I went over to the system's Preferences and to the Look & Feel section. There I selected another theme and all went well > Problem solved. Thanks so much, Ricky
